ABSTRACT:
A process is provided for making strong, permeable nonwoven fabrics having an abrasion-resistant burnished surface. The process involves providing a lightly consolidated or weakly bonded web of thermoplastic synthetic organic fibers, needle punching the web, heating a surface of the needled web, and burnishing the heated surface with a rotating, smooth-surfaced metal roll, which preferably simultaneously cools the web surface.
